Publication number: 20230149045Abstract: A surgical system and procedure are provided for correcting a deformity between first and second bones using an alignment guide based on a correction factor. The alignment guide is used to insert one or more k-wires into each of the first and second bones in a deformed configuration. A correction guide is passed along the k-wires to rotate and/or translate the first bone relative to the second bone into the corrected configuration. An auxiliary correction guide can be passed along the k-wires to further rotate and/or translate the first bone relative to the second bone from the corrected configuration to an adjusted configuration.Type: ApplicationFiled: October 26, 2022Publication date: May 18, 2023Inventors: Daniel Sayger, Michael Chad Hollis, Vernon Hartdegen

Publication number: 20230092178Abstract: Apparatus and methods are disclosed for correcting deformities in a patient's foot. In one example, a metatarsus adductus is addressed using a pin placement guide that is angulated to be placed in alignment with a cuneiform and a metatarsal, such that the TMT joint can be subsequently cut, and the metatarsal moved into proper alignment. Th pin placement guide can be a variable angle guide, or a kit of fixed-angle pin placement guides can be provided.Type: ApplicationFiled: September 21, 2022Publication date: March 23, 2023Inventors: Michael Campbell, Scott Shawen, Daniel Sayger, Michael Chad Hollis

Publication number: 20220370211Abstract: Methods and apparatus are disclosed for excising a joint between first and second bones to define a resected joint, approximating the first and second bones to reduce the resected joint, and fixing the first and second bones relative to each other. The excising step can be performed using a cut guide that is movable from a first orientation to cut the first bone to a second orientation to cut the second bone. A compressor block can be driven over temporary fixation members that extends into the first and second bones to reduce the resected joint. A staple, along or in combination with other fixation elements, can then permanently fix the first bone to the second bone.Type: ApplicationFiled: May 19, 2022Publication date: November 24, 2022Inventors: Michael Campbell, Scott Shawen, Daniel Sayger, Michael Chad Hollis
